Report #3140

[bug\_fix] CreateContainerConfigError

Run \`kubectl describe pod\` to identify which ConfigMap or Secret key is missing. Create or update the referenced ConfigMap/Secret with the missing key, or correct the environment variable reference in the Pod/Deployment spec. Make sure \`envFrom\`/\`valueFrom\` names and keys match exactly.

Journey Context:
You apply a Deployment that mounts environment variables from a ConfigMap. The pod stays in CreateContainerConfigOff. \`kubectl describe pod\` reports "couldn't find key LOG\_LEVEL in ConfigMap app-config". You check the namespace and the ConfigMap exists but its key is \`log\_level\` \(snake\_case\) while the Deployment references \`LOG\_LEVEL\`. You either update the ConfigMap key to \`LOG\_LEVEL\` or change the \`valueFrom.configMapKeyRef.key\` to \`log\_level\`, re-apply, and the container is created successfully.
